Digital Baseband ASIC For Dolphin Chipset

The DBB03A is a baseband ASIC for the "Dolphin" reference design. The firmware for the Dolphin reference design resides in the ROM-based program memory of the DBB03A and thus CAN be readily interfaced with a TRF6903 single-chip RF transceiver to generate a frequency hopping Wireless UART "Dolphin" reference design chipset.
The DBB03A baseband ASIC in addition to being a RF baseband processor is also responsible for Communications with an external host/system micrcontroller. In a typical end user application, the Dolphin chipset will be connected up to an external host/system Microcontroller that will send configuration messages, RF transmission messages into the Dolphin chipset, or receive status, RF messages received from the Dolphin chipset.
Any catalog low-cost host/system Microcontroller CAN be interfaced to the Dolphin chipset as long as the Dolphin host Interface protocol for Communication is adhered to. (See Application Note Dolphin - Frequency Hopping Spread Spectrum Chipset Host Interface Protocol TI Literature SWRA043) Texas Instruments recommends its ultra-low power MSP430 series of Microcontrollers to Interface with Dolphin.
The Interface between the DBB03A baseband ASIC and an external host/system Microcontroller is a simple UART consisting of RX and TX data lines. (See Application Note Interfacing Dolphin to an External System Microcontroller TI Literature SWRA045).
The Wireless UART Dolphin chipset is a true Data-In/RF-out and RF-in/Data-out solution with all aspects of data management and frequency hopping implemented in firmware residing on the DBB03A. The DBB03A baseband ASIC contains the complete firmware for Dolphin (PHYsical, MAC and the Data Link layer), while the application layer protocol is handled by the external Host/System Microcontroller
